What Is Security Laminated Glass?
Definition and Core mechanism
Security laminated glass is a composite material made by permanently bonding two or more pieces of glass through a high-molecular polymer intermediate layer. Its safety performance depends on:
Energy absorption mechanism: The intermediate layer (PVB/SGP/EVA) absorbs impact kinetic energy through viscoelastic deformation
Fragment binding effect: After breaking, the glass fragments are firmly bonded by the middle layer
Structural integrity maintenance: Even if it breaks, the overall structure can still be maintained to resist penetration
End manufacturing processUltra-high pressure lamination technology of security laminated glass
Pressure: 12-15bar (1.2bar for ordinary process)
Temperature: 145±1℃, precisely controlled
Vacuum degree: ≤0.1mbar (eliminating bubbles)
Nano-interface enhancement technology
Treatment of glass surface with silane coupling agent
Carbon nanotubes are added to the middle layer (the bonding strength is increased by 40%)
Military-grade edge processing
Micro-chamfering processing (0.1-0.3mm)
Polyurethane edge sealing (Weather resistance increased by 3 times)
Special application solutions

Features
High Security
After the glass is broken, the fragments are still adhered to the intermediate membrane to prevent splashing and wounding.
Can withstand a certain impact force, reduce accidental damage.
Strong Impact Resistance
Intermediate film (such as PVB, SGP) can absorb impact energy and improve the impact resistance of glass.
Good Sound Insulation Performance
The intermediate membrane can effectively reduce noise and improve the sound insulation of the building.
Package
